中压加氢裂化装置催化柴油改质的工业应用

介绍了在柴油十六烷值与其化学组成关系的基础理论研究成果的基础上，在装置催化剂体系和反应机理不改变，分馏系统流程不做改造前提下进行催化柴油改质的工艺探索。实际工业应用表明：在中压加氢裂化装置上进行的原料切换过程整体平稳，装置产品结构分布合理，产品质量稳定可控，改质后柴油十六烷值提高了17个单位，多环芳烃脱除率为99.98％。     

Correcting for survey effects in pre‐election polls

Pre‐election polls can suffer from survey effects, causing biases in forecasted election outcomes. We advocate a simple methodology to estimate the magnitude of survey effects, by collecting data both before and after the election. This method is illustrated by means of a field study with data concerning the 2009 European Parliament elections in the Netherlands. Our study provides empirical evidence of significant positive survey effects with respect to voter participation, especially for individuals with low intention to vote. For our data, the overall survey effect on party shares is small. This effect can be more substantial, for example, if political orientation and voting intention are correlated in the sample.

我国汽车改装现状与前景的探讨

随着我国国民经济的不断发展,汽车制造业也正在壮大,但国内的汽车改装行业还处在一个微妙的地位,不仅缺少这方面的研究,同时也缺少改装这方面的技术,改装的技术标准、改装鉴定标准和评价标准。然而我国的汽车改装发展之路会是怎么样?笔者就我国汽车改装的现状与前景加以探讨。     

货币危机模型在中国当前的表现

传统的货币危机模型由于前提假设过分简化而与现实生活相去甚远,这些前提也许只能勉强存在于西方发达国家,在发展中国家不可能存在.依据我国国情对传统货币危机模型进行修正,通过修改模型框架中的利率平价条件(引入制度摩擦系数),构建符合中国实际的货币危机模型,可以得出如下结论:在当前制度前提下,如果我国受到投机攻击,固定汇率持续的时间可能会因制度摩擦系数的存在而被有效延长,但是制度扭曲的代价却是积累更大的金融风险.

Habit Formation and the Theory of Addiction

In the light of repeated rejections of the Hall (1978) version of the life cycle‐permanent income hypothesis and other empirical puzzles, the habit formation hypothesis has increased in popularity since the 1980s. However, existing formulations of habit persistence do not always perform well empirically. This paper pursues two objectives: (i) to outline the habit persistence hypothesis, and (ii) to review the theory of addiction with a focus on issues of relevance to the theory of consumption. In the literature on addiction, two research traditions are discernible: rational addiction and myopic addiction. The former approach emphasises forward‐looking behaviour and defines memory loss as a univariate process. The latter relies on multiple objectives and highlights the role of contractual behaviour. The paper argues that future research in consumption with habits ought to pay more attention to non‐separabilities, allow for multivariate processes when modelling memory loss and consider rational habit modification.
